DLW21SN921SK2L

Common Mode Chokes Overview

The DLW21SN921SK2L is a two-line common mode choke manufactured by Murata Electronics, designed for surface mount applications. It operates within an impedance range of 920 Ohms with a tolerance of ±25 percent at a test frequency of 100 MHz. The component supports a maximum DC current of 160 mA and features a maximum DC resistance of 950 mOhms. It functions reliably across a temperature range from -40°C to +85°C. The device utilizes a wirewound structure housed in an unshielded 0805 package measuring 2 mm by 1.2 mm by 1.2 mm.

Common Mode Chokes Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Check for any recent lifecycle changes or obsolescence notices before finalizing procurement plans. Ensure storage conditions align with moisture sensitivity level requirements.

Common Mode Chokes Selection Notes

Select this component when space constraints require a small 0805 footprint for common mode filtering. Consider the 160 mA current rating to ensure it meets the operational load without saturation. Evaluate the 920 Ohm impedance value against target noise frequencies to confirm adequate attenuation. Verify that the unshielded design does not interfere with nearby sensitive components.

Common Mode Chokes Part Context

This part belongs to the DLW21S series of common mode chokes from Murata Electronics. The series focuses on providing effective electromagnetic interference suppression in compact form factors suitable for modern electronic devices. These components are engineered to maintain signal integrity while reducing unwanted noise in high-speed digital circuits.

Common Mode Chokes Replacement Considerations

Consult official Murata substitution guides for verified alternatives. Cross-reference impedance values and physical dimensions to ensure compatibility. Verify that any substitute component meets the same current and temperature specifications.
